Over the past week, workers have been filling the sinkhole with a limestone-sand mixture and using two Bobcats to spread it below. The interesting thing about the Bobcats is that they are being operated remotely ? one of them has a roller compactor, while the other has a traditional bucket. Overall, significant progress has been made and, as you can see from the below video, the Bobcats no longer need to be lowered into the hole, instead requiring just a ramp to climb down.

Stay tuned for next week’s update on the Corvette sinkhole ? GM Authority will be here to keep you up to date.
